today we're gonna talk about radon now
before we get into this I do want to say
that this is just for a friend of mine
we're gonna try to resolve an issue that
they have right now and I've actually
solved an issue for them five years ago
as well in their other house so they
asked me just to come in and do this so
I'm not a licensed professional so I
suggest if you are having issues to seek
somebody in that field that knows
obviously all the ins and outs and who's
done the training but this is just kind
of a I've had success in the past trying
it again and it's it's worked out so
let's run through this now I'm going to
grab my super high tech digital drawing
here so just to kind of give you the lay
of the land we are standing right here
this is us now so what we have this blue
box is what you see over there behind
that door that's the original house so
that has a full basement then over in
this green patch that's an addition that
they've done with a crawlspace
there's no access to that at all so
we'll show you what we how we resolve
that issue over there and then rate
underneath me is a crawlspace so we're
gonna access at that point we're gonna
go underneath show you what it was
before and what we did to to resolve the
issue
so let's buzz in under here follow me
[Music]
good thing we know where this is because
you'd never find it if you did had to
pull the freezer out come on in
let's follow me so obviously this is it
all finished here's some photos of what
it looked like before and you can see
that it was just a gravel floor now it's
a very clean crawlspace there's no mold
there's no moisture or anything but
that's problem with radon is you'll
never know it's there until you test it
right but it's obvious why they had
radon so for us to do this or solve this
issue is fairly straightforward right
because if they had no vapor barrier no
Concord or anything right so this is
what we've done as you can see when we
laid this is 10 mill poly and you can
see that we Walt we had to go around and
clean all the footings really well
vacuum them off
crawl around and it wasn't necessarily
me doing it all you know I had help and
thanks to my brother and and some of my
crew for helping out but you can see the
acoustical sealant all the way around so
let's get a little closer so you can see
what we've done
so in behind me you can see this
ductwork here yeah
if you pan to your left you can see the
inline fan and we just exhausted that
outside
so obviously that took just a little bit
of investigation before we started
bucking holes in the wall and then if
you pan to your right the ductwork just
goes down we did a splitter because
there's this footing down the middle
we had to split that so we just split
the pipe
and then we just we we wanted a little
bit of airspace from underneath so it's
not the Polly's aren't sitting super
tight but that's on purpose so that it
can draw air from underneath and the
pipe just sucks out from two locations
before we act before we started the
remediation in this space we set up this
we set up the radon tester and its
measured in Piko Curie's per liter so
yeah I won't go a ton into the detail of
what it all means if you're at this
point you probably know enough about it
but you can see that this down here it
was 4.18 which I would say is pretty
darn high pretty scary especially
long-term effects right back where we
started let's go downstairs now
so we're in the basement my friends took
the liberty of going ahead and getting
this polyaspartic or this epoxy flooring
done so that would they did that on
their own I think it's a good idea is
just a way to seal the floor up right
because there's no vapor barrier under
this slab for sure right and what they
told me is the levels that they had up
on the second floor so that's way up
high was in between like 2.2 and 2.5
before all this started so that's and
typically you want to test it down low
so we knew there is an issue so over
here just in behind this door is a
mechanical room there's not much there
I feel like down the road we have some
backup like if the levels for some
reason go higher or we need to do more
we have an option to do more and it
wouldn't be that hard that area is one
of them we didn't touch that there's no
sump or anything in there it's just a
couple furnaces right over here is an
access panel that we've sealed up in
there's just a concrete pit but we it's
not a sump there's no actual place for
water to come in it's just a concrete
pit and you see some plumbing pipe that
goes in goes from somewhere to an
addition or wherever right so we sealed
the top of that it's also can be
accessed like if you pan over this way
so in behind just in this room is the
washroom so there is an access panel
it's just a little cubby kind of
in-between this space in the bathroom
where that that pit is so that wasn't a
big deal but if you look over over here
this is the old this is still the
original foundation but on the other
side of that is that other crawlspace
and there's no access to that yeah so it
took some exploration to figure out how
to get and pull air out of that
crawlspace and actually we did it right
inside these closet doors
so this ended up being an ideal location
we checked out a few other sources where
we thought we could pull air out of none
of them really worked dealt like there
was a trunk line in behind you that went
through the wall but it was perfectly
sealed so luckily we found this room and
we just punched a hole out to the left
and we figured well since there's no
access at least get a hole in there get
some piping in there and just pull from
pull air out of that and dump it outside
then if you look down this is a sump and
this is a legitimate sump so it's dirt
and stuff in there so we sealed up this
pluck'd in the old pipe came up then we
teed off we went to the right and then
you can see the exhaust fan there and we
just we had to dump it out underneath
the the deck at the front but we just
did what we could do so now the other
day when we checked here the levels were
at between 0.4 and 0.5 so the levels are
down my friends are happy I'm happy they
have they own the tester so that if they
want to just keep it testing keep
checking if the levels go up at least we
have we can do more right we can we can
always just do a little bit better job
but it's definitely we've done a group I
think we've done a great job so far and
yeah so that's how we did it you know
obviously like I said before check some
professionals out but you know the
physics is pretty simple suck get the
air out before it just keeps rising up
into your house and breathing that stuff
in forever so thanks for tuning in
